Not exactly, the heated water in the tank it self is roughly the desired temperature of the thermostat, there is a variable of 5 to 15+ degrees depending on its calibration. there are other considerations i.e. water heater tank insulation - hot water pipes being exposed to cooler temperatures thus cooling the water in the pipe - the farther distance that the water travels from the heat source, the cooler the water will be at the spigot.

follow this steps and fix it. God bless you

If there is no hot water, first push the reset button on the high-temperature cutoff; test the thermostat and replace if faulty (see below). Test the heating elements and replace if faulty (see below).
If there is not enough hot water, adjust the thermostat settings. As needed, reset, test and replace thermostats and heating elements if faulty.
If the water is too hot, adjust the thermostat settings and reset. Test and replace the thermostat or high-limit cutoff (see below).
An electric water heater is a 240-volt appliance that can deliver a fatal shock. Always turn off power to the heater at the electrical panel 585dc480-4881-44a8-afda-7267c0f3de26.jpgbefore beginning work, and verify that power has been shut off. Make sure others in the house know not to restore electricity prematurely. If you have any doubt as to whether electricity has been turned off, seek professional assistance.

Tip

Electric Hot Water Heater Temperature Adjustment


If your electric hot water heater is not getting your water hot enough or your water is too hot then you can make the adjustment easily yourself. There are a few things that you may need to know to do this. I will go over where the thermostat(s) are located and also how to make the changes.

The first thing to remember is to make sure that the power is turned off to the hot water heater before you attempt to open any of the covers and make any adjustments.

The next thing is to locate the covers which are over the thermostats and the elements. There are two on most hot water heaters, one for the top and one for the bottom. One or two screws hold these covers in place. They will look like this when you look at the front of the hot water heater.

When you have the cover removed you will see that the top thermostat, reset safety control and the element look like this.

The bottom thermostat and element look like this.

If you need to reset the hot water heater you push the red button on the top thermostat in hard till it clicks. To change the temperature setting on the thermostat you need to take a screw driver and turn the dial to the desired temperature either higher or lower as you prefer.

The elements can also be checked by using and ohm meter and checking for resistance across the two terminals of the element. If you get no resistance or a high resistance the element is no good. A normal reading with most meters will be somewhere in the 8-25 ohm range. This even gives a bit of buffer for different meters and the possibility of them being a bit out of calibration.

For most people a simple adjustment of the temperature settings will be sufficient to give you the results you want. Remember that you may need to adjust the thermostat for both elements to get the desired result. Also remember that you can get a longer time before you run out of hot water if the water is hoter and you mix more cold into it. The downside of that is the chances for scalding are greatly increased with hotter water. If you have small children or elderly adults, think carefully about what very hot water can do to them.

For higher efficiency you also want to keep the water temperatures as low as possible to reduce the residual heat loss of the stored hot water.

Whirlpool hot water heater puts out overly hot water


1) Make sure factory-supplied insulation and cover are reinstalled over thermostats, or cooler room temperature causes thermostat to under-approximate tank temperature, and this causes overly hot water.
http://waterheatertimer.org/images/Tank-with-insulation-2-600.jpg
2) Replace both thermostats.
Sticking thermostat can seem to act normally when tested, but when left alone it sticks, causing runaway overheating.

Brand new heater seems to run out of hot water when ran for awhile and seems to take long to recover. also is it supposed to be noisy when running it almosy sounds like water running but its not


You have some hot water so that says specific things:
-Upper element is working.
-Electricity to water heater and circuit breaker are good
-You don't report a leak so TP valve is good
-You are not experiencing overheating event
-ECO reset button is not tripped
-Insulation and covers are in place so thermostat not exposed to cooler temperatures that would cause thermostat to misread temperature and cause overheating.

That leaves 6 suspects listed in order of ease:
1) Leaking faucet or broken water line that is running hot water all the time and tank cannot keep up.

2) Thermostats set too low. Turn power OFF, open covers and check each thermostat setting.
http://waterheatertimer.org/How-to-adjust-temperature-on-water-heater.html

3) Loose screw or loose wire at upper thermostat, lower thermostat, or lower element. Turn power OFF and tighten screws, and look for signs of high heat and burning, especially on lower element.

4) Upper or lower thermostat is bad. Replace both thermostats for $28 and see if that corrects problem.
Parts available at home center, hardware, or plumbing supply
http://waterheatertimer.org/How-to-replace-thermostat-on-electric-water-heater.html

5) Defective wire between upper and lower sections of tank: If this is the case, and water heater has 2" foam insulation, then tank usually replaced since insulation is too dense to drop another wire. Call for manufacturer for warranty information. Do a full troubleshoot using multimeter.

http://waterheatertimer.org/How-to-troubleshoot-electric-problems-with-water-heater.html

6) Lower element is burned out. Test lower element. Replace lower element. Rheem elements are 4500 Watts and are available at home center, hardware, or plumbing supply

I have an AO Smith Model EES 52 917 hot water heater. This morning my hot water suddenly disappeared. I have tried resetting the breaker with no luck.. I am not sure what else to try.


You have electric water heater.

Inside the upper panel on water heater is a thermostat with red reset button.
1) Click the reset.
2) Put insulation back over thermostat so it is not exposed to cooler air, so it reads correct temperature.

After resetting thermostat, you will have hot water.
The reset automatically clicks off when thermostat detects temperatures in excess of 150 degrees.
The re-set is a safety device, and it keeps everything safe.
If reset will not 're-set' with cold water in the tank, then thermostat is bad, replace thermostat.
You can repair electric water heater yourself following steps on links below

http://waterheatertimer.org/How-to-replace-thermostat-on-electric-water-heater.html
http://waterheatertimer.org/How-to-troubleshoot-electric-water-heater.html

If the reset clicks off again, just reset it
This is not a dangerous situation
Reset thermostat as many times as necessary until you can fix the problem

If you have trouble fixing the problem, add a comment at bottom of this page and it sends me an e-mail and I will help further

I have a reliance 606 electric water heater. This is my problem. The water gets unbearably hot then I have to reset the reset button on the water heater. I am thinking that I need to replace the heating...


you need to replace the thermostats. the elements are working, as your water is getting hot.

I would replace both upper and lower thermostats. be sure to set the temps the same for both.

the thermostats sit against the tank and read the tank temperature. if one is malfunctioning, they will over heat the water, causing you to get severe hot water.

also as a precaution, I would replace the temperature and pressure relief valve. if your water is getting that hot, and this has not "popped" then it is time to replace it.
